LOOM-SHUTTLE-THREADING DEVICE.

SPECIFICATION forming part of Letters Patent No. 386,816, dated July 31, 1888.

(No model.)

To all whom it may concern.-

Be it known that I, FLORYAN GRUBINsKI, a subject of the Czar of Russia, residing at the city of Warsaw, in the Empire of Russia, have invented certain new and useful Improvements in Loom-Shuttle-Threading Devices, of which the followingis a specification.

Heretofore it has been customary to draw the end of the thread in a shuttle through au aperture in the side of the shuttle by placing the end of the thread at the inner end of the aperture in the shuttle, placing the lips on the outside of the shuttle at the opeuing,and then drawing in the breath, whereby the thread was drawn through the aperture. This has the disadvantage, however, that particles of the thread, fibers, dust, die., are also drawn into the throat and lungs of the operator,and cause diseases.

The object of my invention is to provide a new and improved device for drawing a thread through the aperture of the shuttle from the inside to the outside, which device is simple in construction, can be easily applied, and works automatically.

The invention consists in the combination, with a spring suction apparatus, of an automatic latch for releasing` the spring suction device automatically after the desired compressi0n,whereby a vacuum is suddenly produced, which draws the thread through the aperture in the side of the shuttle.

The invention also consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and then pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of my improved device for drawing threads through the apertures of shuttles, showing` the same eX- tended-that is, in position before it has been applied. Fig. 1L is a longitudinal view and cross-section of the fixed stem in the handle. Fig. 2 is a longitudinal sectional view of the device, showing the suction part compressed. Fig. 3 is a top view of the shuttle and my device, showing the manner in which the saine is applied.

Similar letters of reference indicate corresponding parts.

The truncated cone a is made of sheet metal and is provided atashort distance from its upper end with a transverse apertured partition, ai. The tube c is passed longitudinally through thecone and project-sa short distance from the upper end of the same, said tube being securely fastened in the upper truncated part of the cone and to the partition a. A short distance above the partition a2 the tube c is provided with a transverse partition, c', closing'the tube c, and above said transverse partition c the tube is provided with a series of apertures, c?, so as to establish communication between the upper part ofthe tubec and the upper part of the cone. A ring, bt, fitting snugly on the tube c,is mounted to slide on the same, and on said ring b* a circular plate, b2, is held, and on the saine the middle portion of a disk, b, of leather, rubber, or other tight elastic material is placed and is held on the same by a metal cap, b3, placed upon the eeutral portion of said disk of rubber or leather. The upper edge of the said disk of rubber or leather is placed on the lower edge of the cone a, and is held on the sanieby a clamping-ring, a'. A spiral spring, e, surrounds the tube c within the cone, one end ofthe spring resting against the underside of the partition c?, and the other end resting on the cap b3.

To the ring b'L a tube, f, is secured, which projects downward and tits snugly on the outside of the tube c in such a manner that it can slide on the same. The lower end of a square stem, g, fitting Within the tubular handle g, is screwed in the bottoni of the said tubular handle, that part of the stem g' within the upper part of the tube c being rounded, but flattened on one side, the rounded part resting against the inner rounded surface of the tube Gand being adapted to slide on the same. rlhe tube c is provided at its lower end at one side with the slot c", and some distance above the same in the opposite side with the longer slot, c5.

The latch l is pivoted in the longitudinal slot gz of the stein, and on the upper end, h2, of said latch a spring, g, acts, which spring is fastened to the flattened side of the stem g. On the inside of the tube c a projection, c, is provided, which is located from the lower end of the tube c a distance equal to the distance which the apparatus is to be compressed. On the upper end ofthe tube c a nipple or tip, d,

of rubber or other suitable material is placed.v

The operation is as follows: The parts of the instrument being in the position shown in Fig. 1, the open end of the rubber tip or nozzle is placed against the side ot' the shuttle B, so as to bein line with the thread aperture C in the side of said shuttle. The handle g is then pressed in the direction of the arrow x', Fig. 1, whereby the leather or rubber disk b is brought into the position shown in Fig. 2 and the spring e compressed. As shown in Fig. 1, the edge of the upper end, h2, of the latch It rests against the bottom edge of the exterior or sliding tubef, and is kept in this position by the spring g3. By pressing the handle in the direction ofthe arrow m the stem g' and the latch h in the same are moved in the same direction and the end of the latch, acting on the end edge of the tubef, moves thesaid tube in the same directionthat is, the said tubef slides on the central tube, c. When the parts are in the position shown in Fig. 2 and the handle is pressed still farther in the direction of the arrow x, the projection c6 acts ou the lower end, h, of the latch h and presses the same in the direction of the arrow x2, Fig. `2, whereby the upper end of the latch h-that is, the Y end resting on the end of the tube f-is moved in the inverse direction of the arrow x2 sufficiently to disengage the upper end of saidlatch from the end of the tubef. `The springe expands and throws the plate bz and the center ofthe flexible diskib inthe inverse direction of the arrow x into the position shown in Fig. 1, whereby a Vacuum is produced in the conical casing a and the end of the thread D in the shuttle is drawn through the aperture C. All that is necessary to draw the thread through the aperture in the shuttle4 is to place the tip or nozzle against the aperture in the side ofthe shuttle and push the handle g, whereby the centery ofthe rubberfor leather disk is pressed inward, the spring compressed, .and' thel parts then moved automatically in the inverse directionl to create a suction.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a-vessel containing a spring and having a compressible bottom, of a tube passed central] y through said l latch-disengaging mechanism, substantially as herein shown and described.

2.
